Most browsers on the Pi are very basic and not suitable for viewing things like the MX user interface. Do you have particular requirement for using a browser on the Pi rather than on your PC? Many people don't even run a graphical interface on the Pi at all.

There is no indication of an error while attempting an upload to PWS Weather. If you turn on debug logging, the uploads will be logged including the response from PWS Weather.

It's not a good idea to edit the Cumulus.ini file directly unless it's for a setting which can't be edited via the user interface. The realtimegauges.txt setting is configurable from the user interface, as are the vast majority of settings. It's a good idea to restart MX after changing a setting, as many of them require a restart to take effect.

Have you looked at the station settings page to make sure your settings are still correct for your station? You could also check that PWS Weather is still configured correctly.

Update - I changed the USB port in the config file and, for reasons I cannot explain, the data is now getting sent to my PWS online weather. It must have somehow changed port numbers when I went to the powered USB connection. So, for the moment, two of my three problems are solved. The most important is that the data is getting online so my drip controller can see it. The config.ini problem is gone as well. I just cannot view the actual data.

When I was using Cumulus on my PC, it was all good. Display was fine, graphics were great and it posted to my PWS online fine. The ONLY reason I went to the RPi was to keep the weather station posting data to PWS online for my drip controller when we are away from home. We throw the PC in the safe (it's a VERY cool, very small new Intel NUC) when we are away. So in the big scheme of things, MX is doing what I need it to do. The graphics are gravy. I honestly don't think it's the RPi browser, it seems to work fine for everything else. But I guess it could be.

Yes, the Pi is a great platform for running MX. It's not such a great platform for running a web browser. Your reasons for wanting to use a browser on the Pi aren't clear to me - could you explain? Have you actually tried opening the MX user interface running on the Pi from a browser on your PC? Do you not currently have access to any computer other than the Pi at the moment?

Steve - the only reason that I try to look at the web browser is to look at the real time gauges display. I enjoy the graphics - you did a great job with those. But as I said it's more important that the data gets to the PWS website so my drip controller can see the data. All that was working fine until 2 days ago when the data at my PWS account went stale again. I just noticed it today. I got the same errors as before; then I realized that I had gone back to the original .ini file which still had the realtime FTP enabled. So I went back in and turned those off:

And then restarted CumulusMX. So this will be the real test. If the data doesn't go stale, I'll stay with the RPi. If it does go stale, I'll switch to using Cumulus on my PC. Not sure how I can get the PC to see the RPi, but I'll give it a try.

To be clear, when you say restarted, do you mean that you stopped Cumulus to edit Cumulus.ini, and then started it again after the edit? You need to have a Cumulus stopped while doing the edit as otherwise it will overwrite most of the settings when you stop it.

To access the user interface on the Pi from a PC, put http://a.b.c.d:8998 into your browser, where a.b.c.d is the IP address of the Pi.

Steve - yes I exited Cumulus MX, made the changes to the .ini file and restarted. So far all is well on the PWS website. Updating nicely every 30 minutes. Historically it will hang up after 2 or 3 days. I will attempt to get the PC to view the RPi interface when I get home tonight. Not sure how to locate the a.b.c.d IP values. I've been using "localhost" when I used the RPi browser. And based on previous blogs, I changed the port to 9999 when I start the program. Thanks for all your help.

Thanks - worked like a champ. My PC displays the data no problem. Here's the only weird thing (and at this point it's a "don't care") - after I got the displays working on my PC, I went back to the RPi and typed in the IP address and it showed all the graphics as well, but only one time. I closed out the browser, and then went back to it later on and it would only give me the blank browser page with no graphics. Oh well, seeing them on my PC is actually a bonus since I spend most of my computer time there.
